Hi there, It is a big first step that you are able to recognise that you have a problem. You are quite right, you could be having depression. It is likely that the depression itself is making you irritable, because it makes you feel like everyone and everything else is getting in the way when you just want to be alone. A divorce is a major life event, and even when you think you are handling it fine, it is a highly stressful situation to be in. If you are prepared to get someone else to help you with the problem, then I would suggest either a psychologist or a counsellor. They would be able to talk you through your thoughts, and how to handle day to day things so that you don t get overwhelmed. If you are really hesitant to meet someone, then try out methods like mindfulness, which involves training yourself to pay attention to the present instead of ruminating about the past, worrying about the future, or following a negative train of thought. It also involves accepting whatever thoughts that come without judging yourself or what you did, and being kind to yourself the way you would to a good friend. There are a lot of online resources out there on mindfulness because of the explosion of research on it in recent years, some websites even offering free online courses on it. Another medical problem that can cause irritability is high thyroid hormone levels, but it also causes many other symptoms like excessive sweating, increased appetite, diarrhoea, weight loss and poor sleep, which doesn t seem to be the case in you. That can easily be ruled out with a simple blood test if you are unsure. Persevere with finding something that works and you will get better. You have already overcome the biggest hurdle, which is recognising that there is a problem. Hope this helps, please let me know if you have further questions. Regards, Dr. Teh
